We divide 217970 by 70
We want to figure out the number of times 217970 can be divided by 70.

Going ahead to step 1:
2 divided by 70 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 70

Advancing to step 2:
70 can be fit into 21 0 times, resulting in a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Bring next digit (7) of the dividend behind the 21 and repeat the process: 217 / 70

Going ahead to step 3:
70 can be fit into 217 3 times, resulting in a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 210 from 217 and we're left with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 70

Let's proceed to step 4:
The number 70 fits into 79 1 times, leaving a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
If we subtract 70 from 79, we get 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 70

Step 5:
97 divided by 70 is 1 with a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 311.0
The remainder is 27 after subtracting 70 from 97.
Take the next digit (0) from the dividend and append it to 27, then repeat: 270 / 70

Let's proceed to step 6:
270 divided by 70 is 3 with a remainder of 60.
The number 3 becomes the next digit in our result. 
Result so far: 3113.0
If we subtract 210 from 270, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 7:
600 divided by 70 is 8 with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 3113.8
If we subtract 560 from 600, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
70 can be fit into 400 5 times, resulting in a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 3113.85
Subtract 350 from 400 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 9:
The number 70 fits into 500 7 times, leaving a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 3113.857
Subtract 490 from 500 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
70 goes into 100 1 times with a remainder of 30.
The next digit of our result is 1. 
Result so far: 3113.8571
Subtract 70 from 100 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 11:
300 divided by 70 is 4 with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 3113.85714
Subtracting 280 from 300 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 12:
If we divide 200 by 70, we get 2 and a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 3113.857142
If we subtract 140 from 200, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 13:
If we divide 600 by 70, we get 8 and a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 3113.8571428
If we take 560 away from 600, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 14:
70 can be fit into 400 5 times, resulting in a remainder of 50.
The next digit of our result is 5. 
Result so far: 3113.85714285
Deduct 350 from 400 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final result is 3113.85714285 with a remainder of 5e-08.
